FRED GRUBER, on NEWARK, NEW JEasEYQ VALVE MECHANISM. i

To alltvhom it may concern:

Be it known that I. Fnnn GItfTBER, a citizen of German residing at Newark, county 7 of Essex, and state of New Jersey, have invented certain new and useful Improve ments in Valve Mechanism, of which the the valve mechanism for controlling the ini take and, exhaust of the motive fluid. v

The invention has for an object to provide a construction and arrangement of the valve and operating means therefor in which the entire series of valves for an engine of any number of alined cylinders are mounted as a unit, in the engine, which unit may be easily detached and replaced for purposes of repair or for other purposes.

For further comprehension of the invention, and of the objects and advantages thereof, reference willbe had to the following'description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a diagrammatic side View of an internal combustion on the line 2-2 of Fig. 1.

Fig. 3 is a detail plan view of the valve 1 block.

Fig. 4: is a front view thereof. Fig. 5 is a side view thereof. 7 Flg. 6 is a perspective view thereof.

In; the drawings 1 indicates the crank case 7' of a four cylinder internal combustionfengine and 2 the cylinders thereof. The carbureter is indicated at3, the intake manifold at land the exhaust manifold at 5,

one of the pistons being shown at 6 in Fig. 2. As shown most clearly in this latter figure the cylinders are formed on one side with fa laterally projecting ledge. 7 which" extends across the face of all four. cylinders and may be cast integral with the latter as indicated in the drawings or formed separate and bolted in place, the top face of this ledge being flush with the upper endof the body of each cylinder.

This ledge forms a support for the valves whichare set therein, the valves being all carried in an elongated block v8 having ta-- perin'g, side and end walls whichres't's in e Specification of Letters rateht. P f f g ne 8 1 Application filed October 17,1919. s rial No; 331,426."

complementary slot cut through the ledge from top to bottom', the heightof thelblock and ledge belng equal and the top surface of the block eing flush withthe top surtion. V

.Formed in this block, and-suitably spaced the length thereoffare valve chambers 9 and 10 for intake valves ll and exhaust valves 12 respectively, the block being formed'with the lateral apertures 13 and 14 which extend inwardly from the side thereof to the valve chamben, which latter are formed by bowing downwardly from the top surface of the block. 'The outer wall of the ledge 7 is formed withsuitable registering openings to receive the branches of the intake and exhaust manifolds, as'indicated in Fig.

2. The valves are of the puppet typeand seat upon the top surface of the block and have stems 17 and 18 which extend downwardly through the chambers 9 and 10 and project at their lower'endsfrom the under surface of the block, the valves being yieldingly held in closed position by means of coiled compression springs 20 which surround the projecting stems and bear between collars 21 on'the latter and bushings 22 on the under surface of the block. The lower ends of these valve stems project into close proximity to plungers 23 operated in a well known manner by a crank shaft, not shown.

when the valves are'lifted from their seats, suitable partitions dividing. the cap to prevent communication through'the latter between the cylinders.

To provide for the apphcationofia cooling medium the inner side of the block 8 is formed with a longitudinal recess 28 while a like longitudinal recess 29 is formed in the adjacent wall of the ledge 7.

It'will be apparent that by removing the cover the block may be readily lifted from place and with it the entire series of valves.

1 Havingthus described" my invention what "I claim as new and desire to protect by Let- I ters Patent of the United. States is as follows: i

1. In'an internal combustion engine, a se= 60 faceof the ledge when the block is in posiries of intake and exhaust valves, an elon- -ried by said block.

gated block having tapering side and end walls and lateral apertures in which said valves are mounted, and means for detachably mounting said member on the engine. 2. In an internal combustion engine, a series of cylinders, a ledge extending along said cylinders, an elongated block having tapering side and end walls and lateral apertures removably carried by said ledge, and

a series of intake and exhaust valves car- 3. In an internal Combustion engine, a sesaid cylinders, an elongated block set'in'a slot in the said ledge with its top facefiush with the top face of said ledge, and a series cylinders and having its top face flush with i the upper ends of the cylinder bodies, an elongated block removably set in a slot in the said ledge with its top face flush with the top face of said ledge, a hollow cap ex tending across the upper end of the cylin- I ders and the said ledge, and a series of valves carried by said block and opening into the said hollow cap. ries of cylinders, a ledge extending along In testimony whereof I have aflixed my signature.
